1, Figs. 1 and '3, is the main driving shaft journaled in the machineframe 2 and carrying the driving pulley 3.

4 is a cam shaft for the press A, and 5 the cam shaft for press B. Theseshafts are continuously driven when the machine is in The constructionof press A comprises the slides 12, Figs. 1, 2, 3 and 21, and theextended tool carrying gate 13 or other like movable support to whichthe lower end of the slides are secured. These slides are guided in theuppef boxes 14, Fig. 2, and the lower boxes 15, Fig. 21, of the pressframe.

16 and 17 are toggle arms, the upper end of the former is pivotallyconnected to the pin 18 located in-a stationary part of-the press, andthe lower end of the latter is pivotally connected to the pin 19 in thebracket 20 secured to the gate 13, and the inner end of the arms arepivotally connected to the pin 21.

22 is a linkconnecting the toggle arms with the lower end of the branchlever 23 (see also Fig. 21), which lever carries the roll 24 operatingin the cam groove 25, Fig. 3, in the vertical face of the cam plate 25on the shaft 4. The upper or branch ends of lever 23 are mounted on therod 26 journaled in the machine frame.

horizontal portion 13 of the The counterbalance levers 27, carrying theadjustable weights 28, are mounted on the rocker shaft 29 journaled inthe machine frame.

30, Fig. 21, are rods whose upper ends are pivotally supported to theinner ends of the levers 27 and project freely into holes provided inthe upper ends of the gate slides 12, and carry springs, one, 31, onlybeing shown, which spring is located between the head 30 of the rod andthe inner end of the plug 32, so that when the gate descends the springsin the slides will be compressed to serve as shock absorbers on thereturn of the gate. 1 33, Figs. 3, 21 and 26, is a lever carrying at itslower end the roll 34 operating in the groove 35 formed in the face ofthe cam plate 25. The upper end of this lever is secured to the paperfeeding rock shaft 35 journaled in the machine frame.

36 and 37, Figs. 3 and 21, are paper feeding levers whose upper ends aresecured to the rock shaft 35", and whose lower ends carry the paperfeeding mechanism mounted on the slides 38 and 39 operatively located inthe inner face of the sides of the press. The forked end of the leversembrace the roll 40, Fig. 28, mounted on the slide to which are alsopivoted the upper end of the links 41, while their lower ends arepivoted to the shoe 42 adapted to be brought into contact with the edgesof a paper strip to feed the same a predetermined distance.

43 are supporting braces connecting the gate to the upper ends of theslides 12.

44, Figs. 1, 2 and 3, are three blanking punches mounted in the innerends of the horizontal portion of the ate 13 and are verticallyadjustable therein through the medium of their threaded shank 44 and thenuts 45. i

46 is the die plate secured to the bed of the press, and 47 is thestripper overlying the die plate between which die plate and stripperthe paper strip 48 is fed. The crimping or creasing mechanism engagesthe paper strip before it reaches the blanking dies just described.

Referring to Fig. 21, 4,9 is a large sprocket wheel on the crank shaft 4carrying the chain 50 to drive the smaller sprocket wheel 51 integralwith the sleeve 52 rotatably mounted on the stud 53. This sleeve carriesthe spiral gear 54 meshing with the spiral gear 55 on the shaft 56journaled 1n the standards 57,Figs. 3 and 8, in which are also rotatablyjournaled the short vertical shafts 58 carrying the s iral gears 59 meshing with the spiral gear 60 on shaft 56.

61, Fig. 8, are spindles in the ends of shafts 58 adapted to support thelower crimping dies 62 by a ball and socket joint connection as shown.

63 is a bracket secured to each spindle and side of each of the crimperdies. The rotation of the spindle carrying shafts 58, to-

gether with the rolls 64 and the spiral track 6 of the crimper dies,will impart an undulatory or rocking movement to the crimping dies forthe purpose presently to be described.

65 is an overlying 'plate over which a paper strip is fed and having theholes 66 within which the crimpers operate.

67 are the upper crimpers carried by the horizontal portion 13 of thegate of press A,

Figs. 2 and 3, through which their shanks 67 project. Referring to Fig.7, these upper crimpers are yieldingly supported in t e housings 68 bymeans of the springs 69.

Both the upper and lower crimpers have the radially arranged steelblades 70 and the intermediately and radially arranged fiber blades 71,which fiber blades form anvils for the steel blades and thus avoidcutting the paper. The alternate arrangement of the steel and fiberblades will force each alternate crease r in opposite directions asshown at Fig. 29. When the upper crimpers are brought down into workingrelation with the undulating lower crimpers, only a small portion of theblades of either set of crimpers will engage with the paper, owing tothis rocking movement of the lower crimpers.

This rocking feature is important, especially in crimping very heavypaper, as it will always insure auniform crimp throughout the entirecircle, which it would be extremely diflicult if not impossible tosecure such a result were the entire surfaces of bothsets ofcrimpersbrought in contact with the paper.

rotatable carrier' 73, Figs. 2 and 30, one set of which will always beunder the blanking f dies when said dies are brought into'action.

The plaiter dies or plaiter ring dies have the tilting and radiallydisposed fingers 74 and "the central opening 75. The rotation of thisplaiter ringjdie carrier to bring one set 1 of plaiting dies under theblanking dies at 2 the same time that a set is under the plaiters.

or plaiter heads presently to bedescribed, is

:as follows: 76, Figs. 1, 3, 26 and 27, is index wheel secured to thevertical shaft 77,

560 which shaft is journaled in the upper bracket 78 and lower bracket79 with-the plaiting die carrier secured to the lower end of said shaft.The index wheel is located in its three positions by meansof notches.80, Fig. 26, and the detent 81 normally held against the wheel by thesprings 82 and is slidably mounted in the stationary chair83. 84 is asegment swiveled on the hub of the index wheel 76 and carries thepivotally supported bell crank lever 85, to which lever is pivoted thedownwardly spring actuated locking pin 86 adapted to register with anyone of the three holes 87 in the inner rim 7 6 of the index wheel 76. 88is a chain connecting the free end of the bar 89 with the bolt 90 in oneend of segment 84, and the chain 91 is fastened to the bolt 92 in theopposite end of -the segment and to the bolt 93 midway of the bar 89.The bar 89 is actuated to have a longitudinal movement through themedium of the lever 94 whose lower end is pivotally supported on the in95, Fig. 21, and is operatively connected y the roll 96 with the camgroove 96", Fig. 21, in the vertical face of -the cam plate 97 mountedon the cam shaft 4 of the press A. 98, Figs. 21 and 26, is a verticalrod whose lower end is journaled in the bracket 99. 100 is a slidemounted in screw 104 adapted to engage the pin 105 of the slide ordetent 81 to force said detent back out of contact with the wheel 76when the raised portion 97, Fig. 3, of the cam plate 97 engages with theroll 101 of the before mentioned slide 100. When the index wheel 76 isreleased in the manner just described, the bar 89 will be actuated inthe direction of arrow f, Fig. 26. This movement of the bar will,through its chain connection 91, and the engagement of the lockmg .pin86 with one of the holes 87, rotate the index wheel 7 6,'shaft 77 andthe plaiter die carrier 73. When the said carrier has been thus rotatedone-third of a revolution, it will bring one of the notches 80 in theperiphery of the index wheel 76 in position to be l1%&ged by the detent81. Just previous to sue, engagement, the hook end of the slid; ing .bar196, Fi 27 will enga e with the cam face 103. o arm103 (see a so Fig.26) which will cause said bar 106 to move outward, and, as the other endof this bar is connected with one arm of the bell crank bar106 willactuate said bell crank lever and cause the withdrawal of the locking ordrivingipin 86, which will take place simultanementioned, the/chain. 91was unwound. In

as reverse movement of the bar 89,- the chain 91 will wind about thesegment while the chain 88 will unwind therefrom. While the segment isbeing returned in the manner described, the spring actuated driving pin86 will ride on the upper face of the inner rim 7 6 until it arrivesopposite a hole therein which it will enter in readiness for anotherturn of the index wheel.

The press B, Figs. 2 and 3, is constructed similar to the press A,having the slides 107 in boxes 14, horizontal gate 108 or other likemovable support connected by the toggle arms 109 and 110 with the/upperstationary part of the press.

111 is a link connecting the toggle arms with the lower end of thebranch lever 112, which lever carries the roll 113 engaging with the camgroove 114 in the vertical face of the cam plate 115 mounted on the camshaft 5. The upper branch ends of the lever 112 are journaled on the rod116. The counterbalance levers 117 carrying the Weights 118 are mountedon the shaft 119. The shock absorbing mechanism connecting the innerends of these levers with the upper ends of the slides 107 is the sameas that previously described for press A, one of the spring controlledrods, 120, Fig. 1, only being shown.

121 are brace rods supporting the gate to the slides.

122, Figs. 1, 2 and 3, are three plaiters mounted in the inner end ofthe gate 108. These plaiters, together with the plaiter dies 72, beforedescribed, being full described in my former application file May 23d,1910, No. 562,857, a further detailed description of them is unnecessaryat this time. In Fig. 3 the plaiter fingers 123 are opened in readinessto engage a crimped blank on the plaiter dies, while in Fig. 1 theplaiter fingers are shown closed. The fingers are opened, Fig. 3, whenthe plaiter finger spindle 123 strikes against the stop 123*. When oneof the group of three plaiter dies are rotated by its carrier under thethree plaiters 122, the gate will descend and force a crimped paperblank, overlying the plaiter dies, through said dies into three formingdies located in the die conveyer 124. This die conveyer, Figs. 4, 5 and6, is, for convenience of construction, built up of the sections 124bound together by the external band 125, and the interior band Ml of theopenings 126 of the conveyor are permanently filled with the formlugdies 127 and are retained therein by the screws 128. The conveyer ismounted on the rollers 128", Fig. 2, carried by the standards 128",supported on the bed C of the machine. This die conveyer is indexed tobring three of its dies onto the anvil 129, Fig. 3, for the operation ofplaiting, forming and heading the rim of a cup, presently to be morefully described, as followsz Referring to Figs. 2,19 and 20,130 is ahorizontally operated curved lever journaled on central support 131 andcarrying the two pawls 132 and 133, the former adapted to engage thestuds 134, Fig. 19, on the exterior of the conveyer, and the latter toengage with the studs 135 on the interior of said conveyer to pull saidconveyer a distance equal to the distance between the center of one rowof die openings, 126, which die openings are supposed to be filled withforming dies, to the other row of said openings or, in other words, froms to a. The horizontal lever 130 is "actuated by the vertical'lever 136,

' 3, whose upper end is journaled on the F1 rod 137. 138 is a rollcarried by this lever which engages with the cam groove 139 in.

the rear vertical face of the cam plate 115. The lower end of thislever, Fig. 20, forms a ball and socket connection with the carrier 140.141 is a ball projecting from the horizontal lever 130 which forms a.ball and socket connection with the other part of the carrier 142. Theclamped end 140 of the carrier 140 frictionally connects these twocarriers together with a gri sufiicient to enable the lever 136 tonormaily operate the horizontal lever 130. 143 is a thin metal strip oncarrier 140 that separates the spring armatures 144 on the carrier 142so that, should the rotatable forming die conveyer 124 meet with anyobstruction liable to break the lever 136, or do any damage to any otherpart of the mechanism connected with the die conveyer, the extra strainon said lever will slip the frictional connection between the carriers140 and 142 far enough to disconnect the metal strip 143 and allow thearmatures to spring together and close an electrical circuit, and stopthe machine. 145, Figs. 19 and 20, is a recoil stop lever to locate thedie conveyer in operative position by having its free hook end engagewith the square base portion 134 of the studs 134 of the conveyer. Thislever is pivoted to lever 146, which, in turn, is pivoted to the stud147. Lever 145 is normally held against the outer rim of the forming dieconveyer by the spring 148. 149 is a dead stop lever pivotally supportedon the bolt 150 located in a stationary part of the press B, and isnormally held against the outer rim of the conveyer by the springs 151.152 is a sliding bar carryin on its inner end the pin 153'to engage t einner face of the lever 145, while the end of the bar projecting throughthe machine frame carries the pin 154, seen also at Fig. 1. The taperend of the slide bar 155, which bar is secured to the rack 156, isadapted to engage this pin and draw the lever 145 out of engagement withthe forming die conveyer 124 for the purpose presently to be described.The slide bar 155 and rack are actuated by the lever 157, Figs. 22 and23, pivoted on the stud 158, the upper end carrying the roll 159, Fig.1, to engage with the groove 160 in the cam plate 161 mounted on shaft5. The simultaneous movement of levers 136, Figs. 3, 19 and 20, andlever 157, Fig. 1, will carry the curved horizontal lever 130 and theslide 155 in the direction of arrow h, Fig. 19, both to retreat lever145 and to bring the pawls132 and 133 of lever 130 over two of the studsof the die conveyer. The return movement of lever 130 will carry saidconveyer the required distance in the direction of arrow g. The retreat,at the same time, of the -slide 155, will release lever 145 and allow itto spring back against the outer rim of the conveyer in readiness toengage with the base 134* of one of the conveyer studs as soon as thepawls of lever 130 have embraced said studs. The instant said pawls arein place, the free end of lever 149 will have dropped back of the studengaged by the pawl 132 to prevent the retreat of the die conveyor. Asthere is considerable momentum in the die conveyer when the lever 145takes hold to locate said conveyer, it would cause a shock by its suddenstoppage. but for the shock absorbing spring 162 located in the end ofthe adjusting screw 163 carried by the lever 1 16. 147 is an adjustablestop screw against which the lever 146 will rebound and rest when thedie conveyer is at a standstill. When the plaiter die carrier 73 hasrotated a group of three plaiter dies under the plaiters 122 with thecircular paper blanks i overlying the dies as shown at Fig. 2, the gate108 will descend with said plaiters and force the blanks through theplaiter dies into three forming dies carried by the die conveyor 124,which dies, at the time, will be resting upon the anvil 129. Theplaiters will then retreatand leave the plaited cups in said dies, whichdies will be advanced by the die conveyer to the next position presentlyto be explained. To prevent the plaited cups being drawn out of-the dieswhen the plaiter carricr starts to rotate, the cups are held in theirdies by air suction. A small opening is provided in the bottom of eachforming die and holes are provided in the anvil at the point that theforming dies will rest when the plaiters are operating, and pipescommunicating with said holes in the anvil and an air exhaust pump (notshown) Will hold the cups in the dies by suction while the dies remainunder the plaiters, one of said pipes. 164, only being shown at Fig. 3.The next turn of the die conveyer will bring the dies containing theplaited cups, just described. under the forming punches 165 removablylocated in the opening m of the punch conveyer 166. This conveyer isintermittently rotated to bring three punches into position to enterthree dies containing the plaited cups as' follows: Referring to Figs. 1and :2, 167, 168, 169 and 170 are vertical shafts carrying at theirupper ends the sprocket wheels 171, 172, 173 and 174, the latter servingas an idler or tightener. The lower ends of these shafts also carrysprocket wheels, two, 175 and 176, only being shown at Fig. l. 175 isthe drive chain for said shafts. The rack 156 engages the pinion 177 onthe lower end of shaft 167 so that when the lever 157 is actuated toactuate the slide 155, before described, it will also actuate theforming punch conveyer the proper distance required. The

punches are removably secured in the conveyer by means of the wirespring clips 17 9, Fig. 17, located in the openings m of the conveyeradapted to engage the groove j, Fig. 31, of each punch. 180, Figs. 1, 2,3, 10 and 11. is a stationary guide support for the punch eonveyer andis located in rear of the plaiters and over the die conveyer.

The manner of forcing the punches out of their conveyer and into thedies containing the plaited cups is seen more clearly in the enlargedviews shown at Figs. 10 and 11. 181 are three plunger holders secured tothe underside of the press gate 108, and 182 are combined plungers andpunch ejectors operatively mounted in these holders and are backed up bythe springs 183. one only of said springs being shown. 184 are lockingfingers pivotallv supported in the plunger holders and have the lip 7..Fig. 32 adaptcd to normally rest op the tapered rim n,

I Fig. 33. of lhe upper end ofthe plungers,

and are normally and removably held thereagainst by the springs 185.When the gate 108 descends. the shoulders 0 of the plun- {z'crs contactwith the top of'the punches and force said punches out of their conveyerwhen they will drop into the plaited cups 7) within the dies 127 restingon the anvil 129, which anvil is secured to the bottom B- of the press;B. The plungers follow up the punches as the gate descends to give therequired pressure to the cups. Should, however. the dies not be directlyunder the punches so that the plungers will meet with a resistanceliable to do damage to the mechanism connected with the process offorming the cups. the fingers 184 will be forced outward by the reversemovement of the plungers and the springs 1323 back of said plungers willabsorb the shock due to the resistance the plunger-s may have met with.The wires 9 are connected to the plungers and are part of an electricalcircuit so that immediate notice is given of the trouble. and where tolocate it. If the plunger-s meet with no obstruction. the engagement ofthe fingers with the plungcrs will be sufiicient to carry the plungersdown and dislodge the punches, and before the ends of said plungersagain contact with the dies to effect the necessary pressure, the lowerends of the fingers will have entered the mouth of the depressiblelocking rings 186 which will effectually prevent their becoming.unseated from the upper ends of the plungers when the final pressure isapplied. The locking rings are located on the punch conveyer support orguide by the bolts 187 and springs 188 so that said rings will followdown with the gate of the press. Previous to the dislodgment of thepunches from their conveyer, the plaited cups are partially unseated orlifted up a short distance in order that the punches may be well seatedin the cups before the final pressure is applied. By this arrangement,the pressure is applied equally over the whole surface of the cups,whereas, if the cups were seated in the dies when the punches enteredtherein, the pressure would be applied first at the mouth of the cupswhich would have a tendency to distort or draw the paper at that point.The partial and temporary unseating of the plaited cups is effected asfollows: 189 are movable die bottoms, and 190 are plungers verticallyoperating through the base B of the press and the anvil 129 as shown atFig. 10 and having the tapered end 190 adapted to enter the taper hole189 in the lower end of these bottoms, so that said bottoms may beaccurately seated when the plungers 190 are retreated. The lower ends ofthese plungers are (see also Fig. '11) pivotally connected with oneendof the levers 191 whose opposite ends are held in frictional contactbetween the plates 192 mounted on the shaft 193, which shaft iscontrolled and actuated by the gate 108 through the medium of theconnecting rod 194, seen also at Fig. 1. When, therefore, all three ofthe cups have been lifted up as shown by the center one of the threecups in Fig. 10, the dies will drop into said cups, and when theplungers 182 descend and reengage the punches to effect the necessarypressure, the bottoms 189 and'the plungers 190 will also be carried downby reason of the frictional support of said plungers 190. The adjustableset screw 195, Fig. 11, will regulate and limit the distance that theplaited cups are lifted.

The next operation connected with the formation of the cup is formingthe bead v on the rim as shown at Fig. 13, or trimming the rim when thecup has the outward curved lip 'v' as shown at Fig. 1-1. The threeheading or trimming tools, Fig. 12, are carried by the gate 108 and arelocated immediately back of the cup forming tools just described. Theseheaders comprise the head portion 196 to which are plvotally supportedthe fingers 197, whose lower; curved edges m are normally held incontact with the top edge of the plungers 198 by the springs 199. Theouter shell or housing 200 is secured to the press gate 108 and to thehead 196. 201 is a header cap which floats on the lower end of theplunger and is maintained there by the wire 1' headed over at the lowerend and having the nuts t at the upper end. The header ring 202 isfitted snugly to the mouth of the cap 201. The dies shown at Fig. 12have the recessed mouth it which is entered by the header to form thebead t, Fig. 13, on the cup P while the cups P previously described havea curved lip as shown at Fig. 14. The dies for the beaded and curved lipcup may be made exactly alike except the recessed mouth. The engagementof the fingers 197 with the upper end of the plunger, combined with theinward pressure of the springs, is sufficient to effect the beading ortrimming of the cup, but any undue resistance that would result indamage to the tools would dislodge the fingers and allow the extrapressure to be absorbed by the spring 202. In utilizing these tools fortrimming the edge of the curved lipped cup, Fig. 14, the header ring 202is removed and the ring cutter 203, Fig. 32, is substituted therefor.The right hand header tool is shown in the act of forming the bead onthe cup. In actual practice it will be understood that all three toolswill be carried down by the gate at the same time. 'It will also beunderstood that when mention is made of the headers, it implies thetrim-' ming feature'whenever the trimming ring is substituted for theheader ring.

After the operation of heading ortri-m- "ming just described, the nextoperation will be to extract the punches from the dies with the papercups adhering thereto. The same number of extractors are employed asthere are plaiters and headers. These extractors comprise the housings204, Figs. 1, 2, 3 and 15, secured to the rear portion of the gate 108.'

205 are plungers slidably mounted in the housings and are backed up bysprings, one only, 206, being shown. These plungers also slide throughthe rings 207 secured to the brackets 208.

209 (see also Fig. 35) are hook fingers pivotally supported on theplungers and are normally forced outward a predetermined distance by thesprings 210. i/Vhen the gate descends, the end of the plungers willenter the mouth of the punches, as seen at Fig. 15, far enough to allowthe hook end of the fingers to spring out and engage the lip w, Fig. 31,of the punches, and on the return stroke of the gate the punches arelifted out of the dies and reseated in the punch conveyer. As soon asthe punches are thus seated, the projections n, Fig. 35. of the fingerswill engage the incline y of the rings 207 and release the fingers fromcontact with the punches while the gate is returning to its upper normalposition. While the punch conveyer is under the extractors it is alsolocated in the stationary guide 211, Fig. 17, which guide is supportedpm the standards 211" and 211 and is intended to keep the punch openingsor seats in alinement with the extractors, and also to prevent springingup of the conveyer when the punches are drawn up and seated therein. hisguide also supports the ring supporting brackets 208.

204, Fig. 15, is a housing similar to the extractor housings and itcarries the plain locating plunger 212 guided in the standard 211, sothat, in case the seats m of the punch conveyer do not aline with thepunches in the die conveyer, this locating plunger will first enter anempty unch seat of the punch'conve er and recti y any errors ofalinement y drawing the punch conveyer into position both for the unchextractors to reseat the forming punc es in their conveyer at one end ofthe press gate, and ejecting them therefrom into the forming dies at theother end of said gate As before mentioned, the finished cups adhere to.the punches when said punches are taken out of the dies. To insure thisadherence and also to assist the extractors so as not to put too muchstrain on the extractor fingers, the followin mechanism is employed:Referring to igs. 15 and 16, 213 is a connecting rod pivotal y supportedto the gate 108 and to the crank collar 214 on the shaft 215 carryingthe cams 216. 217 are okes embracing these cams in which are Journaledthe rolls 218 to engage with said cams. The upper or spindle ends 217 ofthese yokes are adaptedto contactwith the underside of the-die bottoms189 so that the instant the press gate starts to retreat with theextractors, the spindle ends 21-7 wi1l,at the same time assist theextractors in withdrawing the punches from the dies and maintainingcontact between the punched cup and said punches. The standard 219 inwhich the shaft 215 is journaled also affords a temporary supportfordies while under the punch extractors; After the punches with the cupsare located in the punch conveyer, said conveyer is again ad vanced' torepeat the operation of extracting three more punches and the threepreviously extracted are carried step by step toward the front of pressB to meet the dies in the die conveyer again where the operation-ofpushing the punches out of said conveyer into the dies again isrepeated.

Between the point where the punches are extracted from the dies andseated in their conveyer, and the point where they are unseated andforced into the dies, the paper cups are paraflined and discharged fromthe punches as a finished produot,.'as follows:

Referring to Figs. 1 and 2, 220 is a paraflin tank havmg the dependingstuds 220 adapted to have a vertical movement in the standards 221 throuh the medium of the rocking lever 222 and t e connecting rod 223, whichrod connects one end of said lever with the outer end of the arm 224secured to the gate 108 so that, when the gate descends the tank 220will be carried up and the punches with the cups are submerged therein.Any well known means may be employed to heat the parafiin; in Fig. 1 gaspipes 225 are shown for this purpose. 221 is a guide, Figs. 1 and 2,supported by the brackets 221 for the punch conveyer while the same isover the paraflin tank and a short distance beyond. 0 are pipes throughwhich a current of air will be forced into the open mouth of the punchesas soon as they reach this point and eject three finished cups as showndotted, leaving the unches free to reenter the dies. It will be 0 servedin the several views 8% where the punches are shown, and particularlyFig. 31, that the air passages e are provided in the sides of thepunches 'communicatin with the interior through which the air is orceddirectl against the bottom and interior sides of the cup for the purposeabove described;

Referring to Figs. 1, 2 and 3, 226 is a rotary cutter on shaft 227journaled in the standard 228. This shaft carries the sprocket wheel 229and is rotated from the sprocket wheel 230 on shaft 56 through themedium of the chain 231. This cutter-runs close to the inner edge of theblanking die plate 46 for the purpose of destroying the paper scrap bycutting it up into very fine particles which can then be carried away byair suction or in any other suitable manner.

The balance wheel 232 on the cam shaft 4, and the balance wheel'233 onshaft 5 being actuated by the same mechanism to start and sto the gatesof the two presses A and By an also the emergency stops, such mechanismwill be designated by the same reference characters.

Referring to Figs. 21, 22, 23, 24 and 25, 234 are emergency stop leversconnected with the clutch mechanism of each of the presses. Referringparticularly to Figs. 22, 23, 24 and 25 which show the clutch mechanismconnected with press B which, as before mentioned, is a duplicate of themechanism of press A, the stop lever 234 is journaled on an enlargedportion of the cam shaft 5. a is an ordinary half round clutch pinlocated in a semi-circular seat in the shaft so that, when the pinisturned, Fig.
